LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 234,762, dated November 23, 1880. Application filed April 30, 1880. (No model.)

To all whom it may concern:

Be it known that I, THOMAS FITZGERALD, Jr., of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Kerosene -Lamp Burners, of which the following is a specification.

My invention relates to an improvement in lamp-burners in which two separate wicktubes are used and it consists in the arrangement of the wick-tubes, in connection with the construction of the hood or cone.

The invention also consists of a filling-tube inserted through the base of the burner to the body of the lamp, in combination with a plug or stopper attached to the cone in the manner described, by means of which the lamp may be readilyfilled and the aperture of the tube stopped without the use of a screwcap, as generally employed.

Referring to the drawings, Figure 1 represents a section of a burner longitudinally of the width of the wick-tubes. Fig. 2 is a section at right angles to that shown in Fig. 1. Fig. 3 is a view of the bottom of the cap, and Fig. at shows the adaptation of the filling-tube to a single burner.

A represents the cap to be secured to the lamp. B is the hood or cone which covers the wick-tubes. O O are two wick-tubes separated from each other and inserted in the cap A. The said tubes are partially curved,

but their upper portions are vertical, so that the flame will pass directly through the openings in the upper part of the cone B.

E is a partition attached to the cone and extending across the same between the wicktubes 0 O. D is the perforated plate commonly used in this class of burners.

F is a tube extending through the cap A and opening above the plate D. To the inside of the cone B is fixed a plug or stopper, G, adapted to fit into and close tightly the upper opening of the tube F. The cone B is attached to the plate D or to the base of the burner by an intermediate link, H, hinged to the said plate and to the hood or cone B.

By means of the intermediate link, H, the cone B is enabled to be raised so as to bring the plug G over and into the opening of tube F, which would not be practicable if the cone B were hinged directly to the plate D, the opening of the tube F being at an angle with the line-of its length. The projection f of I the inner side of the tube serves also as a guide. for the nozzle of the filling-can.

In theupper part of the screw-cap A are a series of holes, a a, through which air passes to the lamp, or by which vapor is allowed to escape. This is a common device, and it is rendered dangerous in some cases when the light is sought to be extinguished b blowing down the chimney. In order to ob\ tte this difficulty I construct a chamber, I, wh. h consists of a space between the upper p. .e of the screw-cap and another plate above the same. The upper plate of the screw-cap is perforated, as shown at c a, for the escape of heated air or gas from the lamp. The upper plate of chamber I is unperforated; but perforations b I) are made in the sides of the same, through which the heated air or gas passes to the outside of the burner as the flame is blown out, thus preventing liability of explosion of thelamp; or Iarrange a space, I, above the plate of the screw-cap A and perforate the sides of the same, as shown at b, Fig. 2, so that in blowing down the chimney the air will be forced outward.

The wick-tubes O 0, it will be seen, are entirely separate from and independent of each other, so that if it is not desirable to use both at once as a burner either one can be used separately.

Instead of a plug or stopper, G, a cap may be used, fitting over the top of the tube F.

I do not claim two wick-tubes in one burner, I

as I am aware that such is not-new; but

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The separate wick-tubes O 0, having vertical upper ends, in combination with a single cone, B, provided with a partition-plate, E, as set forth.

2. The combination, in a lamp-burner, of a tube, F, passing through the screw-cap, a plug or stopper, G, attached to the cone B, and the double-hinged joint H, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
